Table 4-5. Status Bits Description
Status Variable Byte Reporting
A convenient and more compact way of interrogating the status variable is to test it a byte at
a time using the STn within a read command, where n is used to select the byte to be tested.
For example to read or test the first 8 bits (first byte) of the ST variable status word, use ST1.
Since the status word consists of 4 bytes the relevant part of the word can be read using
ST1 (bits 1 to 8), ST2 (bits 9 to 16), ST3 (bits 17 to 24) or ST4 (bits 25 to 32).
